Compact Microstrip Patch Antenna with Comb-Like Slot for WLAN Applications

A technique to design a compact microstrip patch antenna is presented in this paper. The proposed antenna consists of a comb-like slot patch with inset feeding microstrip line. The proposed antenna shows good impedance bandwidth at the center frequencies 2.44 GHz and 5.61 GHz with good impedance matching. The proposed antenna provides the size reduction of 94.6% while comparing literature one, maximum gains of 2.88 dBi and 4.3 dBi, antenna efficiency of 88% and 98% for both center frequencies, respectively.
